In case the process parameters change, plates are conveniently replaced, added or removed.īaseLine is available with two different plate types: The plate configuration is flexible with many options.
Meets all hygienic heating and cooling requirementsĪlfa Laval BaseLine, with design pressure up to 10 bar (145 psi), meets all the requirements for pasteurization and other heating and cooling duties in hygienic applications.Īlfa Laval BaseLine uses FDA-compliant glue-free gaskets and is easy to open for inspection and cleaning or to clean by means of Cleaning-In-Place (CIP). The Alfa Laval hanging system enables easy handling of the plates in the frame and together with the corner guiding a strong plate pack. This prevents cross contamination between fluids in case of leakage through the plates. The Gemini double wall consists of two plates pressed together. The plates are reversible and have parallel flow, which means only one type of plate is needed. A unique distribution area provides an even flow over the plate surface. Different chevron designs are available, in order to obtain optimal high heat transfer and low pressure drop. The chevron pattern allows for maximum strength at high working pressures. BaseLine is available in two different plate types: Chevron and Gemini. Corner ports and gaskets are arranged so that the two media flow through alternate channels. The corrugation of the plates provides a passage between the plates, supports each plate against the adjacent one and enhances the turbulence, resulting in efficient heat transfer. One unit can contain several heat exchangers, separated by connection plates with interchangeable connections. The frame is designed for mounting on a floor only.
On the largest type, some tightening bolts are equipped with ball bearing washers in order to facilitate opening and closing of the unit. The plates and the pressure plate are suspended from an upper carrying bar and positioned with a lower guiding bar, both of which are fixed to the support column. The plate corrugations promote fluid turbulence and support the plates against differential pressure. The number of plates are determined by the flow rate, physical properties of the fluids, pressure drop, and temperature program. The plates are fitted with a gasket that seals the channel and directs the fluids into alternate channels. The plate pack is assembled between a frame plate and a pressure plate and compressed by tightening bolts. The plate heat exchanger consists of a pack of corrugated metal plates with portholes for the passage of two fluids between which heat transfer will take place.
#ALFA LAVAL HEAT EXCHANGER SELECTION SERIES#
The Baseline Series heat exchanger is a competitive choice for hygienic processes and utility applications, such as simple pasteurization, raw milk cooling, media heating/cooling, and CIP heating. For more demanding hygienic applications the Alfa Laval FrontLine Series is the preferred selection. Working at pressure up to 145 psi, Alfa Laval’s Baseline Series handles not only heating and cooling, but also pasteurization at low flow rates. These heat exchangers can be use in the cooling and heating of applications such dairy, brewery, beverage, and viscous products. Our thermal design engineers will help you design and select the model and configuration that is suitable for your application needs while delivering maximum thermal performance and minimizing pressure drop. High flow turbulence between plates results in higher heat transfer however, the consequence is pressure drop. The result is that the entire heat transfer surface is fully utilized and stagnant zones that can result in fouling are avoided. The chocolate pattern distribution is a design feature that ensures fluids are evenly distributed across the entire plate. For the highest thermal performance and to enable a very close temperature approach, fluids normally run counter-currently through the heat exchanger.īaseLine is available with various pressing depths and angles of the chevron pattern and various shapes of the corrugation which are carefully designed and selected to achieve optimal performance. The sealing between the plates is made of gaskets. The heat transfer area of a gasketed plate-and-frame heat exchanger consists of a series of corrugated plates, assembled between the frame and pressure plates, which retain the design pressure.
